Contractor Wayss and Freytag Ingenieurbau has secured a €420M (£351M) contract in Germany for the construction of a 35km long underground waste water pipeline.
The project will be part of a large scale modernisation of the waste water system of the Emschergenossenschaft water management association. Wayss & Freytag Ingenieurbau is part of the Royal Bam Group.
The pipeline will be layed between Dortmund and Bottrop, running parallel to the River Emscher, and will carry wastewater to a water purification plant near the latter.
Its diameter will vary from 1.6 to 2.8m. Work is due to start next spring and will take five years to complete.
